SU1253783A1 - Lathe for turning internal shaped surfaces of wooden blanks - Google Patents

Description

US.1

The invention relates to the woodworking industry, in particular, to equipment for processing the internal shaped surfaces of wooden blanks.

The purpose of the invention is to increase the productivity of the machine by combining operations.

FIG. 1 shows a lathe general view of FIG. 2; node 1 of FIG. 1 (the cutting head prior to its beginning) i in FIG. 3 - the same in the working position ..

The machine contains a frame 1, a cutting head 2 with hook-shaped cutters 3 and 4, a workpiece clamping mechanism 5, a feed mechanism 6 and a drive 7. The hook-shaped cutter 4 is designed as a double-arm lever mounted on an axis 8, spring-loaded with respect to the cutter head 2 by a spring 9. On a bed 1 mount 537832

Adjustable stop 10, and the non-working end of the cutter A interacts with the stop 0.

The machine operates as follows: 5 3 ohms.

The actuator 7 is turned on and rotation of the workpiece 11 is reported. By means of the feed mechanism 6, the cutting head 2 with cutters 3 and 4 is fed to the end W of the workpiece 11 and the internal surface of the workpiece is cut with cutters 3. By the end of the treatment of the internal surface of the workpiece 11, the cutter is not working 4 tS comes into contact with the stop .10, the cutter 4 rotates on the axis 8 and bores the workpiece 11. After finishing the machining, the cutter head 2 is retracted from the workpiece 11, the cutter 4 under the action of the spring 9 takes the initial position. The workpiece 11 with the aid of the mechanism 5 for clamping the workpiece free of water, is pressed and the cycle is repeated.
